It is very easy to click the wrong button and select 'New Category' rather than 'New Authorized value for.....'. If this mistake is made there is then no delete option to allow you to remove it. This redundant authorized value policy needs to be deleted in the database. Would be good to introduce a 'delete category' button in the staff interface.
+1, this is a fairly common support request from our partner libraries. Gonna rename the bug to specify categories, though
There is an older bug for that - I agree it would be nice to have this implemented. *** This bug has been marked as a duplicate of bug 17355 ***
